Delivering a highly stable 24V DC output at 10A, this premium DIN-rail mounted power supply features an ultra-flexible 1-phase or 2-phase wide-range input. This unique capability allows it to operate seamlessly across varying global electrical line standards or bridge system power grids, offering superior immunity against sudden voltage dips and line surges.
Key Features
-
Flexible 1/2-Phase Wide Input Range: Uniquely designed to accept a wide input range (120–230V AC / 230–500V AC), enabling connection to single-phase or two phases of a three-phase network.
-
Extra-Power Peak Output Mode: Engineered with a built-in power reserve providing up to 150% of rated current (15A for up to 5 seconds) to effortlessly handle heavy-load startups and high-inrush capacitive loads.
-
Excellent Efficiency & Low Heat Loss: Operates at up to 91% electrical efficiency, drastically reducing thermal generation inside control cabinets and cutting operational cooling costs.
-
Selectable Short-Circuit Behavior: Features an adjustable toggle switch allowing technicians to choose between standard constant-current automatic restart or latching shutdown in the event of an electrical fault.
-
Compact, Slimline Profile: Rugged, ventilated metal enclosure optimizes vertical space layout on standard DIN rails while maximizing passive air cooling.
